Influence of Conformation of 9,10-Anthrylene Rotors on Structures and Self-association Properties of Macrocyclic Arylene-Alkynylene Oligomers

摘要

Macrocyclization of 9,10-bis[(3-ethynyl-5-octylphenyl)-ethynyl]anthracene afforded three cyclic oligomers: a dimer, a trimer, and a tetramer. Only the trimer showed significant self-association in solution because of its fully planar structure. Their structures and properties were significantly influenced by the conformation of the 9,10-anthrylene rotors depending on the ring size.
